Under the coordination of Eurecat-CTM, leader of the project, on September 5tht 2018, the first LIFE SOLIEVA meeting was held in which all the partners participated: CITOLIVA-the Olive Oil and Olive Farming Technology Centre, the National Technological Center of Conservation and Food (CTNC), the cooperative olive mill Virtudes, the company Technical and Projects SA (TYPSA) and the Panhellenic Association of Table Olives Processors Packers & Exporters (PEMETE).
The LIFE-SOLIEVA project will provide a solution for the sustainable treatment of wastewater from table olives, through a pioneering technology capable of dealing with the environmental challenges of this industry, and achieve the recovery of compounds of the brine, transforming them into products with high added value for the food industry.
The innovative and pioneering nature of LIFE-SOLIEVA lies in demonstrating the technical and economic viability of an advanced solar evaporation treatment system that intensifies natural evaporation by solar energy and reduces the surface area of conventional ponds in table olive processing waters. In addition, by means of the use of membranes and vacuum concentrators and spray drying, it improves the efficiency of the resources of the table olives since it allows the recovery and reuse in the process of elaboration of a high percentage of water (65%), 30% of salts, 40% of sodium hydroxide (NaOH) and up to 50% of organic compounds of value present in the brine, such as polyphenols, highly polluting, but with a great antioxidant power, which are very important interest for the agri-food industry, and that will be used for the formulation of functional foods such as salsa, masses and dairy products.
The LIFE-SOLIEVA project will not only transfer this technology to other countries that produce table olives, such as Greece and Italy, but it can also be applied to other European agri-food sectors, such as canning.
